Abstract

The study was aimed to improve the productive performance of white laying hens, using two types of medicinal herbs, including turmeric and Artemisia Herba. In the experiment 63 laying hens (white shevar) were used at an age of 24 weeks, hens were divided randomly in to three treatment 21 hens pre treatment with 3 replicate of 7 hens per replicate. A standard ration was used without any addition, which was considered as the control treatment (T1), the basic ration, plus turmeric powder (0.5%) (T2), while the treatment (T3) represented the basic ration plus Artemisia Herba powder by 0.5%. The study included the measurements of egg production, egg weight, feed consumption, feed conversion ratio and egg mass. The results showed a significant improvement (P<0.05) in the characteristics of egg production ratio, feed conversion ratio and egg mass for the treatment with the addition of Artemisia Herba flower (T3) compared with other treatments, and significant decrease (P<0.05) in the amount of feed consumed (T2, T3) as compared with the control treatment (T1), while the results did not show any significant differences to addition of turmeric to the ration (T2) in the productive performance as compared to the control treatment. It was concluded from that the addition of Artemisia Herba to the ration resulted in a significant improvement in most of the productive performance of laying hens as compared to other treatments.

تهدف الدراسة إلى إمكانية تحسين الأداء الإنتاجي للدجاج البياض الأبيض، باستعمال نوعين من الإعشاب الطبية التي تشمل الكركم وإزهار الشيح. استخدمت في التجربة 63 دجاجة بياضة بعمر 24 أسبوع، وزعت بصورة عشوائية بواقع 7 دجاجات لكل وحدة تجريبية و ثلاثة معاملات لكل مكرر و بثلاثة مكررات. استخدمت عليقة قياسية بدون أي إضافة اعتبرت بمثابة معاملة السيطرة (T1)، العليقة الأساسية مضافاً إليها مسحوق الكركم بنسبة 0,5% (T2)، في حين كانت المعاملة (T3) تمثل العليقة الأساسية مضافا إليها مسحوق إزهار الشيح بنسبة 0,5 %. اشتملت الدراسة على قياس إنتاج البيض، وزن البيضة، كمية العلف المستهلك، معامل التحويل الغذائي وكتلة البيض لكل معاملة. أظهرت النتائج إلى وجود تفوق معنوي (0.05>P) في صفات نسبة إنتاج البيض، معامل التحويل الغذائي وكتلة البيض لمعاملة إضافة إزهار الشيح إلى العليقة (T3) بالمقارنة مع بقية المعاملات، كما لوحظ وجود انخفاض معنوي (0.05>P) في كمية العلف المستهلكة لمعاملتي الإضافة (T2،T3) بالمقارنة مع معاملة السيطرة (T1)، في حين لم تبين النتائج أي فروق معنوية لإضافة الكركم إلى العليقة في الصفات الإنتاجية بالمقارنة مع معاملة السيطرة. يستنتج من ذلك إن إضافة الشيح إلى العليقة أدى إلى تحسن معنوي في معظم الصفات الإنتاجية للدجاج البياض الأبيض بالمقارنة مع المعاملات الأخرى.

Abstract

This study was conducted at Poultry farm and Poultry Physiology laboratory /Animal Resources Department / College of Agriculture / The University of Baghdad during a period from 26/September/2013 to 1/June/2014 to find out the association of prolactin (PRL) gene polymorphisms with egg weight of laying hens. Two strains of laying hens, White Leghorn (n=100) and Hy-line Brown (n=60) were used in this study and reared in individual cages .Blood samples were collected from a brachial vein at 41 weeks of age. The PRL gene polymorphisms were determined using PCR-RFLP technique and AluI restriction enzyme. Two alleles C and T and three genotypes wild type CC (homozygous), heterozygous CT and mutant TT (homozygous) have been got. The size of the target gene fragment was 439 bp. A significant (p < 0.05) difference was showed in the Brown strain between genotypes CC and TT, the genotype CC was higher than TT in egg weight ( EW) at 34 week of age, in White strain there was a significant (p < 0.05) differences between CC and CT, also, CC with TT genotypes in EW at 30 week of age. The T allele frequency was 0.66, whereas, C allele frequency was 0.34 for Brown strain. In White strain, the C allele frequency was 0.98, whereas T allele frequency was 0.02. The distribution percentage of polymorphism of PRL gene in Brown strain were 56.60, 37.74 and 5.66 % for CT, TT and CC genotype respectively, whereas, the distribution percentage of polymorphism of PRL gene in White strain were 97.75, 1.12 and 1.12 % for CC, CT and TT genotype respectively, and the differences among percentages was significant (p <0.01). The allele frequency and distribution percentage of polymorphism for PRL gene was measured according to Hardy-Weinberg equilibrium.
